I'm sorry this is going to be a rant with few specifics about the my Xbee issues. The new 3DR radio is on order but it would be lovely if the $$$ Xbee investment would actually be worth it too. Any…Continue

In FBW mode, the APM turns almost any plane into a perfect trainer. My two older daughters (9 and 7) were able to confidently circle over the Berkeley marina.

While filming the protests at Taksim Square, Istanbul Turkey, a DJI Phantom is brought down by police. I'm surprised that he managed to keep the footage. Many people arrested at the protests report having their memory card wiped.

Andreas - I was hoping you could help me with a question I have on my DIY Oak Frame. I read in another thread about the importance of the motors being "equidistance" from eachother. In other words, the frame needs to be sqaure (Arms at 90 degrees from eachotherin a Quad setup). My frame is not perfect. It slightly more rectangular, measuring 16.5" on the long edge and 16.0" on the shorter edge. Have you ever encountered this as a problem with your quadrocopter designs? I read that you would have to adjust the Pitch(?) and Roll(?)?

By the way, I changed my screen name to Acorn in case you didn't recognize me.
